Intro to A & P

Anatomy

The study of internal and external structures of the body and the physical relationships among body parts

study of general form & superficial markings

Regional anatomy

study of specific area of body: like head, neck, trunk

study of structure of individual cells

Histology

study of structure of tissues

Cell physiology

study of function of cells (within & between)

Special physiology

study of function of specific organs

Systemic physiology

study of function of organ system

Pathological Physiology

study of effect of diseases on organ or system functions

Molecular Level

atoms combine to form molecules

Cellular level

cells and their organelles; smallest living unit in body

Tissue level

group of cells working together to perform specialized function

Organ level

organs consist of 2 or more tissues working in combination

Organ system level

organ interactions to form a system

Organism level

highest level of organization; human

Intergumentary system

Major organs: skin, hair, sweat glands, nails

Intergumentary system

Functions: protects against environmental hazards; helps regulate body temperature; provide sensory information

Skeletal system

Major organs: bones, cartilages, associated ligaments, bone marrow

Skeletal system

Functions: provides support & protection for other tissues; stores CA & other minerals; forms blood cells

Muscular system

Major Organs: skeletal muscles & associated tendons

Muscular system

Functions: provides movement; provides protection & support for other tissues; generates heat that maintains body temperature

Nervous system

Major Organs: brain, spinal cord, peripheral nerves, sense organs

Nervous system

Functions: Directs immediate responses to stimuli; coordinates or moderates activities of other organ systems; provides & interprets sensory information about external conditions

Endocrine system

Major Organs: pituitary gland; thyroid gland; pancreas; adrenal glands; gonads (tested & ovaries); endocrine tissues in other systems

Endocrine system

Functions: Directs long-term changes in the activities of other organ systems; adjusts metabolic activity & energy use by the body; controls many structural & functional changes during development

Cardiovascular system

Major Organs: heart; blood; blood vessels

Cardiovascular system

Functions: Distribute blood cells, water, & dissolved materials, including nutrients, waste products, oxygen, & carbon dioxide; distributes heat & assists in control of body temperature

Lymphatic system

Major Organs: spleen, thymus, lymphatic vessels, lymph nodes, tonsils

Lymphatic system

Funnctions: Defends against infection & disease; returns tissue fluids to the bloodstrem

Respiratory system

Major Organs: Nasal cavities, sinuses, larynx, trachea, bronchi, lungs, alveoli

Respiratory system

Functions: delivers air to alveoli (site in lungs where gas exchange occurs); provides oxygen to bloodstream; removes CO2 from bloodstream; produces sounds for communication

Digestive system

Major Organs: teeth, tongue, pharynx, esophagus, stomach, small intestine, large intesting, liver, gallbladder, pancreas

Digestive system

Functions: processes & digests food; absorbs & conserves water; absorbs nutrient (ions, water & breakdown products of dietary sugars, proteins, & fats); stores energy reserves

Urinary system

Major Organs: kidneys, ureters, urinary bladder, urethra

Urinary system

Functions: Excretes waste products from the blood; controls water balance by regulating volume of urine produced; stores urine prior to voluntar elimination; regulates blood ion cencentrations & pH

Male reproductive system

Major Organs: testes; epididymis; ductus deferens; seminal vesicles; prostate gland; penis; scrotum

Male reproductive system

Functions: produces male sex cells (sperm) & hormones

Female reproductive system

Major Organs: Ovaries; uterine tubes; uterus; vagina; labia; clitoris; mammary glands

Female reproductive system

Functions: Produces female sex cells (oocytes) & hormones; supports developing embryo from conception to delivery; provides milk to nourish newborn infant
